Heat-killed Lacticaseibacillus paracasei GMNL-653 ameliorates human scalp health by regulating scalp microbiome.

Background: The equilibrium of the scalp microbiome is important for maintaining healthy scalp conditions, including sebum secretion, dandruff, and hair growth. Many different strategies to improve scalp health have been reported; however, the effect of postbiotics, such as heat-killed probiotics, on scalp health remains unclear. We examined the beneficial effects of heat-killed probiotics consisting of Lacticaseibacillus paracasei, GMNL-653, on scalp health.

Regulatory effects of -GMNL6 on human skin health by improving skin microbiome.

Bacteria response to their environment by producing some compounds which are used in cosmetic and pharmaceutical applications. Some probiotics can regulate immune response and modulate the symptoms of several diseases. Bacteria affect skin response to skin care products.

Evaluation of the antioxidant activity and antiproliferative effect of the jaboticaba (Myrciaria cauliflora) seed extracts in oral carcinoma cells.

It is becoming increasingly evident that certain phytochemicals possess cancer chemopreventive properties. In this study, the antiproliferative activity of extracts from different parts of the jaboticaba (Myrciaria cauliflora) plant was evaluated for its effect on human oral carcinoma cell lines. The cytotoxicities of various plant extract concentrations were examined and the 50% maximal inhibitory concentration (IC50) was determined.

Calyculin A sensitive protein phosphatase is required for Bacillus anthracis lethal toxin induced cytotoxicity.

Previous studies have shown that the Bacillus anthracis lethal toxin can induce both necrosis and apoptosis in mouse macrophage-like J774A.1 cells depending on both the toxin concentration and the phosphatase activity. In this study several protein kinase or phosphatase inhibitors were employed to evaluate the hypothesis that the lethal toxin induces cell death via protein phosphorylation processes.
